Hey, I’ve seen Friday Orchid Blogging as well as the now prototypical Friday Cat Blogging, so I’m adding Friday Glowrocks Blogging, a new, occasional feature of this site featuring images from my collection of fluorescent minerals. Glowrocks is a term I coined for referring to minerals that fluoresce under ultraviolet (UV) lighting.
This week’s entry is a slight closeup of a mineral known as halite. It’s more commonly known as salt, or in this form as rock salt. This halite was deposited around branches of sagebrush near the Salton Sea, and the resultant rock glows bright red-orange under short-wave UV illumination. The dark spot in the upper left is part of the sagebrush.
